IEC 60870-1-2:1989

IEC 60870-1-2:1989 is the technical reference for telecontrol equipment and systems, with a focus on general considerations for preparing specifications. It is relevant when engineering teams, procurement staff, or conformity assessment groups need a structured basis for defining requirements, evaluating proposed solutions, or documenting system expectations. As the guide for specifications within

Telecontrol equipment and systems. Part 1: General considerations. Section Two: Guide for specifications

Purpose of IEC 60870-1-2:1989

The purpose of IEC 60870-1-2:1989 is to help users define telecontrol requirements in a systematic and technically defensible way. In practice, it can support the preparation of engineering specifications, procurement documentation, and documented evaluation criteria for control and communication systems. By setting out general considerations for specification writing, it helps organizations align technical expectations, reduce ambiguity, and improve consistency across design, testing, and acceptance activities.

Compliance applications of IEC 60870-1-2:1989

This reference is commonly useful in workflows where telecontrol equipment or systems must be assessed against formal requirements before purchase, integration, or approval. It may be used by utilities, industrial automation teams, laboratories, and technical reviewers involved in system planning, verification activities, or conformity assessment preparation. For organizations managing complex electrical or control-system projects, IEC 60870-1-2:1989 can serve as a practical compliance reference during technical assessment and specification control.

Benefits of IEC 60870-1-2:1989

Using IEC 60870-1-2:1989 can improve operational clarity by giving stakeholders a common basis for technical validation and specification review. That can support safer project execution, better interoperability expectations, and more consistent testing workflows. It also helps reduce procurement risk by making requirements easier to compare and document. For quality assurance and regulatory preparation, a well-structured specification guide can improve traceability, reduce misunderstandings, and support more reliable acceptance decisions.
